HERBERT B. BLISS, OF NIAGARA FALLS, NEW YORK, ASSIGNOR TO BLISS CONIAINERS,

INCL, OF NIAGARA FALLS, NEW YORK, A CORPORATION OF NEW YOR SHIPPINGCASE.

Application filed June 13,

This invention relates to shipping cases constructed offibre board orequivalent material. It is the object of the present invention to afforda shipping case which is especially adapted for the transportation ofheavy articles, such as automobile bumpers, etc. Articles of this kindpresent a very heavy endthrust on the end panels of the case. Theordinary fibre shipping case is ill adapted for shipping hardware ofthis kind, for while it has been possible to construct ends of pluralthickness the seams have but one thickness and are easily broken.

It has been proposed to provide a shipping provide a shipping case thatcan be constructed of a single blank of fibre board or equivalentmaterial and which results in no waste of material, and which furtherpro vides plural seams and plural joints to withstand the heavy endthrust of bumpers or other heavy hardware.

Referring to the drawings:

Fig, 1 is a plan View of the blank.

Fig. 2 shows the completed case.

Fig. 3 shows the blank partly folded up. Fig. 4 shows the same blankfurther folded u Fig. 5 is a section onthe line 5-5 of Fi 2.

Fi 6 is a section on the line 6-:6 of Fig. "Fig. 7 is asection on theline 77 of Fig. 6.

Figs. 8 and 9 are detail perspective showing how the seams are taken.

therefrom by slots. Each of the supplemental end panels is provided witha corner flap each of the cover flaps is provided with a reinforcingflap 2", while these corner and reinforcing flaps j and i all line upalong The end panels f' have sufiicient length preferably to extend outto the end edges of the blank.

The way the various elements are laid out V in the blank as shown inFig. ,1, the width of the side walls is of course equal to the depth ofthe end wall when these dimensions are the same, and the layout isnicely balanced as in Fig. 1, so that the width of the sup- 7 plementalend panels 9 plus the corner flaps j is just equal to the depth of themain end panels 1; consequently there is no waste of material whatever.However as the vertical seams in the assembled case are the main onesnecessary to be reinforced the length of the end panels are necessarilythe width of the case so that the corner flaps will come into thedesired position on the vertical seams.

Referring to Fig. 3, it will be seen how the parts are folded up. Theside wall 0 is folded up with respect to the bottom wall a and thesupplemental end panels 9 carried by the side wall 0 are turned in, asare also the corner flaps 7', attached to such supplemental end panels.The cover flap h, together with its reinforcing flap i can be turned inat the top.

' Next referring to Fig. 4, the other side wall 6 may be folded up andthe supplemental end panel 9 folded in on the inside of the main endpanel f or on the outside this is optional. As shown in Figs. 4 and 2,the main end panel is on the outside. The 100 against end thrust.

' the three end panels at each end stitched to gether on the ends of thecase, as shown in Fig. 8.

The above arrangement provides three fibre end panels at each end of thecase and provides two vertical wire-stitched seams at each verticalcorner of the case. This obviously makes the case of extreme durabilityThe cover flaps h which are folded in at the top under the cover Wingsprovide a double reinforcing structure at the top of the case near theends. Each one of these flaps is provided with areinforcing flap 2' thatis tucked in the inside ofthe case to further reinforce it whenever thedimensions permit; otherwise they lie flush. The cover wings are thenfolded over and are shown. in the drawings ofsuch width as to form acomplete overlap, but this overlap can be reduced to save material. 4The result is that the top of the case has two thicknesses of fibreboard running the entire length, while at the ends where the strain isgreatestfthere are three thicknesses of fibre board. These two coverwings may be stitched together by the insertion of the blade anvil, asshown in Fig. 10. The cover flaps themselves may be stitched togetherbefore the case is sealed, as shown in Fig. 4. However, this is simplyoptional with the shipper. Where they are stitched together as shown inFig. 4, this adds two more seams which tend to resist any end thrustwhich is calculated to tear the three-end panels apart.

As stated the main end panel f may be on the outside. However, it mayalso be on the inside or in the middle. However, this main end panel maybe long or short according to the dimensions of the box, in which eventit is better to have it in the middle.

What I claim is: 1

1. In a shipping case for the purpose specified, a blank which is scoredand slotted to provide bottom, side walls, cover wings and end panelsprovided with perpendicularly folded corner flaps, the same beingarranged to be folded up and fastened togetheralong the entire flap toprovide two Vertical seams at each vertical end corner.

2. A shipping ease for the purpose specified, having a single blankscored and slotted to provide a bottom wall, two side walls anda coverwing, a plurality of end panels with corner flaps, the same arranged tobe folded up and fastened together to provide a plural ply end structurewith the corner flaps folded perpendicularly and stitched to thesidewalls to form a reinforcing seam for the vertical end corners of thebox. 1

3. A shipping case for the purpose specified, having a single blankscored and slotted to provide a bottom wall, two side walls, a coverwing and a plurality of end panels,

some of the end panels being provided with corner at the end of the.case.

4. In a shipping case for bumpers or other heavy hardware, a rectangularblank of relatively long and narrow proportions with substantiallystraight ends creased longitudinally and creased cross-wise near theends, and slotted from such cross crease to the end in continuation oftwo of the center creases, whereby two side walls, a bottom wall, andcover wings, and at each end of the blank three end panels, two with onecorner fiap each-are afforded, the said end panels arranged to overlapwhen the blank is folded up to provide a three ply end, the said threeend panels being each united to the other to resist the breaking down ofthe box when thesame has been built up.

5. A fibre shipping case for the purpose specified, comprising a singleblank slotted and scored to form two side walls, bottom wall, and acover wing, each of the side and bottom walls provided with endextensions in the blank forming end panels and the blank adjacent thecover wing provided with end adjacent portions forming cover flaps, andboth the cover flaps and some of the end pane ls provided with extendedand scored portions forming respectively reinforcing flaps and cornerflaps, the same all arranged to fold u and be fastened together to givea three- 'p y end structure with overlapping cover flaps at the top ofthe case near the ends, having tucked-in reinforcing flaps and toprovide corner flaps which may be stitched to the adjoining side wallsto provide additional reinforcement for the vertical corners at the endsof the case.
